Lead .NET Full Stack Engineer
We're looking for a Lead Software Engineer to join our team in EPAM Spain in a remote working mode. This is a hands-on individual contributor role for an experienced technologist who will take full ownership of end-to-end application development. You will design, develop and deliver robust, scalable solutions using modern technologies with a strong focus on .NET, cloud and AI-driven tools. This role involves architecture design and technical execution rather than people management or pure consulting, making it ideal for an engineer passionate about execution, quality and technical excellence.

- Leverage AI-assisted development tools (e.g., GitHub Copilot) to accelerate delivery
- Collaborate with product owners and engineering teams to ensure alignment with business objectives
- Write clean, maintainable and well-documented code following best practices
- Conduct code reviews and ensure adherence to quality standards
- Troubleshoot, debug and optimize applications for performance and reliability
- Implement and maintain CI/CD pipelines, containerized services and infrastructure as code
- Advocate and apply modern architectural patterns such as microservices, serverless and event-driven design
Requirements
- 10+ years of hands-on experience delivering full-stack applications end-to-end
- Strong proficiency with .NET technologies and ReactJS for frontend development
- Expertise in Azure cloud services and MS SQL
- Experience using AI development assistance tools (e.g., GitHub Copilot)
- Solid understanding of software architecture patterns and system design principles
- Familiarity with CI/CD pipelines, containerization (Docker, Kubernetes) and DevOps practices
- Strong grasp of infrastructure as code concepts and tools
- Excellent problem-solving and analytical skills with a focus on technical detail
- Ability to work independently and take full responsibility for solution design and delivery
- Effective communication skills for interaction with both technical and non-technical stakeholders
Nice to have
- Experience with event-driven systems, messaging queues or serverless architectures
- Familiarity with security best practices for enterprise-level systems
